AASV Position Statement: Permanent Identification of Swine

Permanent identification of swine is performed to identify individual animals or groups of animals to fulfill interstate transport requirements and provide traceability to protect animal and public health. Common permanent identification practices include tattooing, tagging and ear notching. While tattooing and tagging may occur at any age, ear notching should be performed early and sufficiently prior to weaning such that no open wounds remain at the time of weaning. Clean, sharp equipment must be used to minimize pain and risk of infection.
